Tessitura
Tessitura (from the Italian 'tessitura', meaning 'texture' or 'weave', derived from Latin 'texere', to weave) refers to the most comfortable or predominant pitch range in which a vocal or instrumental part sits, as opposed to the absolute range of the part. A melody might reach a high C but have a tessitura that sits comfortably in the middle register. For pianists, understanding tessitura helps with interpretation: a passage written in the high tessitura of the piano (above the treble staff) will naturally sound bright and penetrating, while low tessitura passages have a dark, rumbling quality, and you should adjust your touch and dynamics accordingly. When accompanying singers, awareness of tessitura is crucial — play more softly when the vocal line sits in its lower tessitura, where the voice is naturally quieter.
